MSS meaning in Computing ?

In computing, managed security services (MSS) are network security services that have been outsourced to a service provider. A company providing such a service is a managed security service provider (MSSP) The roots of MSSPs are in the Internet Service Providers (ISPs) in the mid to late 1990s. Initially, ISP(s) would sell customers a firewall appliance, as customer premises equipment (CPE), and for an additional fee would manage the customer-owned firewall over a dial-up connection.

According to recent industry research, most organizations (74%) manage IT security in-house, but 82% of IT professionals said they have either already partnered with, or plan to partner with, a managed security service provider.

Businesses turn to managed security services providers to alleviate the pressures they face daily related to information security such as targeted malware, customer data theft, skills shortages and resource constraints.

Managed security services (MSS) are also considered the systematic approach to managing an organization's security needs. The services may be conducted in-house or outsourced to a service provider that oversees other companies' network and information system security. Functions of a managed security service include round-the-clock monitoring and management of intrusion detection systems and firewalls, overseeing patch management and upgrades, performing security assessments and security audits, and responding to emergencies. There are products available from a number of vendors to help organize and guide the procedures involved. This diverts the burden of performing the chores manually, which can be considerable, away from administrators.
